rustler is a great first time rc cause my friend has one and he loves it. It is worth it and your local hobby shop should have one in stock ( recommend a 3s LiPo instead of a 2s LiPo ) but make sure that it has a traxxas connector. The rustler is LiPo ready, all you need to do is switch the ESC over to low-voltage detection mode wich is easy to do. The stock tires are good on all surfaces for about a week, then they start to wear away. I recommend getting a pair of Pro-Line 2.8 Badlands for the rear cause the stock front tires last a long time. And for on-road tires, get a pair of the Traxxas 2.8 Anacondas. O ya and get either a venom LiPo of a Traxxas LiPo.
